Abstract
The present work reports the first green synthesis of zinc oxide nanoparticles (ZnO-NPs) using Tecoma stans leaf extract. The TEM images show triangular shape ZnO-NPs with sizes ranging from 15 to 20 nm. The XPS spectrum revealed the presence of Zn and O in the sample. Photoluminescence studies of ZnO-NPs displayed a sharp emission of blue band at 447 nm, attributed to the defect structures in ZnO crystal. The synthesized ZnO-NPs showed excellent antimicrobial activity against 5 bacterial and 4 fungal strains with the highest zone of inhibition (ZOI) of 24 mm and 30 mm being shown against Achromobacter spanius and Penicillium citirinum strain using 1 mM ZnO nanoparticles solution, respectively. Furthermore, the current study reveals that ZnO NPs have prospective uses in various medical and industrial domains, making the study extremely relevant and beneficial to the scientific community.
